Details
File
is a high level abstraction for manipulating files on a virtual file system. File
s are
lightweight, immutable objects that do no I/O upon creation. It is necessary to understand that
File
objects do not represent files, merely an identifier for a file. All file content I/O is
implemented as streaming operations (see GInputStream and GOutputStream).
To construct a File
, you can use: fileFromPath
if
you have a URI. fileNewForCommandlineArg
from a utf8 string gotten from fileGetParseName
.
One way to think of a File
is as an abstraction of a pathname. For normal files the system pathname
is what is stored internally, but as File
s are extensible it could also be something else that
corresponds to a pathname in a userspace implementation of a filesystem.
File
s make up hierarchies of directories and files that correspond to the files on a
filesystem. You can move through the file system with File
using fileGetParent
to get an
identifier for the parent directory, fileGetChild
to get a child within a directory,
fileResolveRelativePath
to resolve a relative path between two File
s. There can be multiple
hierarchies, so you may not end up at the same root if you repeatedly call fileGetParent
on
two different files.
All File
s have a basename (get with fileGetBasename
. These names are byte strings that are
used to identify the file on the filesystem (relative to its parent directory) and there is no
guarantees that they have any particular charset encoding or even make any sense at all. If you want
to use filenames in a user interface you should use the display name that you can get by requesting
the FileAttributeStandardDisplayName
attribute with fileQueryInfo
. This is guaranteed to
be in utf8 and can be used in a user interface. But always store the real basename or the File
to
use to actually access the file, because there is no way to go from a display name to the actual
name.
Using File
as an identifier has the same weaknesses as using a path in that there may be multiple
aliases for the same file. For instance, hard or soft links may cause two different File
s to refer
to the same file. Other possible causes for aliases are: case insensitive filesystems, short and
long names on Fat/NTFS, or bind mounts in Linux. If you want to check if two File
s point to the
same file you can query for the FileAttributeIdFile
attribute. Note that File
does some
trivial canonicalization of pathnames passed in, so that trivial differences in the path string used
at creation (duplicated slashes, slash at end of path, "." or ".." path segments, etc) does not
create different File
s.
Many File
operations have both synchronous and asynchronous versions to suit your
application. Asynchronous versions of synchronous functions simply have _async() appended to their
function names. The asynchronous I/O functions call a AsyncReadyCallback
which is then used to
finalize the operation, producing a AsyncResult
which is then passed to the function's matching
_finish() operation.
Some File
operations do not have synchronous analogs, as they may take a very long time to finish,
and blocking may leave an application unusable. Notable cases include: fileMountMountable
to
mount a mountable file. fileUnmountMountableWithOperation
to unmount a mountable
file. fileEjectMountableWithOperation
to eject a mountable file.
One notable feature of File
s are entity tags, or "etags" for short. Entity tags are somewhat like a
more abstract version of the traditional mtime, and can be used to quickly determine if the file has
been modified from the version on the file system. See the HTTP 1.1 specification for HTTP Etag
headers, which are a very similar concept.

Methods
fileFromPath :: ByteString -> File Source #
Constructs a File
for a given path. This operation never fails, but the returned object might not
support any I/O operation if path is malformed.
fileFromURI :: GlibString string => string -> File Source #
Constructs a File
for a given URI. This operation never fails, but the returned object might not
support any I/O operation if uri is malformed or if the uri type is not supported.
fileFromCommandlineArg :: ByteString -> File Source #
Creates a File
with the given argument from the command line. The value of arg can be either a URI,
an absolute path or a relative path resolved relative to the current working directory. This
operation never fails, but the returned object might not support any I/O operation if arg points to
a malformed path.
fileFromParseName :: GlibString string => string -> File Source #
Constructs a File
with the given name (i.e. something given by fileParseName
. This
operation never fails, but the returned object might not support any I/O operation if the parseName
cannot be parsed.
fileEqual :: (FileClass file1, FileClass file2) => file1 -> file2 -> Bool Source #
Compare two file descriptors for equality. This test is also used to implement the '(==)' function, that is, comparing two descriptions will compare their content, not the pointers to the two structures.
fileBasename :: FileClass file => file -> ByteString Source #
Gets the base name (the last component of the path) for a given File
.
If called for the top level of a system (such as the filesystem root or a uri like sftp: will return a single directory separator (and on Windows, possibly a drive letter).
The base name is a byte string (*not* UTF-8). It has no defined encoding or rules other than it may
not contain zero bytes. If you want to use filenames in a user interface you should use the display
name that you can get by requesting the FileAttributeStandardDisplayName
attribute with
fileQueryInfo
.
This call does no blocking i/o.
filePath :: FileClass file => file -> ByteString Source #
Gets the local pathname for File
, if one exists.
This call does no blocking i/o.
fileURI :: (FileClass file, GlibString string) => file -> string Source #
Gets the URI for the file.
This call does no blocking i/o.
fileParseName :: (FileClass file, GlibString string) => file -> string Source #
Gets the parse name of the file. A parse name is a UTF-8 string that describes the file such that
one can get the File
back using fileParseName
.
This is generally used to show the File
as a nice full-pathname kind of string in a user interface,
like in a location entry.
For local files with names that can safely be converted to UTF8 the pathname is used, otherwise the IRI is used (a form of URI that allows UTF8 characters unescaped).
This call does no blocking i/o.
fileGetChild :: FileClass file => file -> ByteString -> File Source #
Gets a child of file with basename equal to name.
Note that the file with that specific name might not exist, but you can still have a File
that
points to it. You can use this for instance to create that file.
This call does no blocking i/o.
fileGetChildForDisplayName :: (FileClass file, GlibString string) => file -> string -> File Source #
Gets the child of file for a given 'name (i.e. a UTF8 version of the name)'. If this function
fails, it throws a GError. This is very useful when constructing a File
for a
new file and the user entered the filename in the user interface, for instance when you select a
directory and type a filename in the file selector.
This call does no blocking i/o.
fileHasPrefix :: (FileClass file1, FileClass file2) => file1 -> file2 -> Bool Source #
Checks whether file has the prefix specified by prefix. In other word, if the names of inital elements of files pathname match prefix. Only full pathname elements are matched, so a path like foo is not considered a prefix of foobar, only of foobar.
This call does no i/o, as it works purely on names. As such it can sometimes return False
even if
file is inside a prefix (from a filesystem point of view), because the prefix of file is an alias of
prefix.
fileGetRelativePath :: (FileClass file1, FileClass file2) => file1 -> file2 -> Maybe ByteString Source #
Gets the path for descendant relative to parent.
This call does no blocking i/o.
fileResolveRelativePath :: FileClass file => file -> ByteString -> Maybe File Source #
Resolves a relative path for file to an absolute path.
This call does no blocking i/o.
fileIsNative :: FileClass file => file -> Bool Source #
Checks to see if a file is native to the platform.
A native file s one expressed in the platform-native filename format, e.g. "C:Windows" or "usrbin/". This does not mean the file is local, as it might be on a locally mounted remote filesystem.
On some systems non-native files may be available using the native filesystem via a userspace
filesystem (FUSE), in these cases this call will return False
, but fileGetPath
will still
return a native path.
This call does no blocking i/o.
fileHasURIScheme :: (FileClass file, GlibString string) => file -> string -> Bool Source #
Checks to see if a File
has a given URI scheme.
This call does no blocking i/o.
fileURIScheme :: (FileClass file, GlibString string) => file -> string Source #
Gets the URI scheme for a File
. RFC 3986 decodes the scheme as:
URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
Common schemes include "file", "http", "ftp", etc.
This call does no blocking i/o.
fileRead :: FileClass file => file -> Maybe Cancellable -> IO FileInputStream Source #
Opens a file for reading. The result is a FileInputStream
that can be used to read the contents of
the file.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If the file does not exist, the IoErrorNotFound
error will be returned. If the file is a
directory, the IoErrorIsDirectory
error will be returned. Other errors are possible too, and
depend on what kind of filesystem the file is on.
fileReadAsync :: FileClass file => file -> Int -> Maybe Cancellable -> AsyncReadyCallback -> IO () Source #
Asynchronously opens file for reading.
For more details, see fileRead
which is the synchronous version of this call.
When the operation is finished, callback will be called. You can then call fileReadFinish
to
get the result of the operation.
fileReadFinish :: FileClass file => file -> AsyncResult -> IO FileInputStream Source #
Finishes an asynchronous file read operation started with fileReadAsync
.
fileAppendTo :: FileClass file => file -> [FileCreateFlags] -> Maybe Cancellable -> IO FileOutputStream Source #
Gets an output stream for appending data to the file. If the file doesn't already exist it is created.
By default files created are generally readable by everyone, but if you pass FileCreatePrivate
in flags the file will be made readable only to the current user, to the level that is supported on
the target filesystem.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
Some file systems don't allow all file names, and may return an IoErrorInvalidFilename
error. If the file is a directory the IoErrorIsDirectory
error will be returned. Other errors
are possible too, and depend on what kind of filesystem the file is on.
fileCreate :: FileClass file => file -> [FileCreateFlags] -> Maybe Cancellable -> IO FileOutputStream Source #
Creates a new file and returns an output stream for writing to it. The file must not already exist.
By default files created are generally readable by everyone, but if you pass FileCreatePrivate
in flags the file will be made readable only to the current user, to the level that is supported on
the target filesystem.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If a file or directory with this name already exists the IoErrorExists
error will be
returned. Some file systems don't allow all file names, and may return an
IoErrorInvalidFilename
error, and if the name is to long IoErrorFilenameTooLong
will be
returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
fileReplace :: (FileClass file, GlibString string) => file -> Maybe string -> Bool -> [FileCreateFlags] -> Maybe Cancellable -> IO FileOutputStream Source #
Returns an output stream for overwriting the file, possibly creating a backup copy of the file first. If the file doesn't exist, it will be created.
This will try to replace the file in the safest way possible so that any errors during the writing will not affect an already existing copy of the file. For instance, for local files it may write to a temporary file and then atomically rename over the destination when the stream is closed.
By default files created are generally readable by everyone, but if you pass FileCreatePrivate
in flags the file will be made readable only to the current user, to the level that is supported on
the target filesystem.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If you pass in a non-Nothing
etag value, then this value is compared to the current entity tag of the
file, and if they differ an IoErrorWrongEtag
error is returned. This generally means that the
file has been changed since you last read it. You can get the new etag from
fileOutputStreamGetEtag
after you've finished writing and closed the FileOutputStream
.
When you load a new file you can use fileInputStreamQueryInfo
to get the etag of the file.
If makeBackup
is True
, this function will attempt to make a backup of the current file before
overwriting it. If this fails a IoErrorCantCreateBackup
error will be returned. If you want to
replace anyway, try again with makeBackup
set to False
.
If the file is a directory the IoErrorIsDirectory
error will be returned, and if the file is
some other form of non-regular file then a IoErrorNotRegularFile
error will be returned. Some
file systems don't allow all file names, and may return an IoErrorInvalidFilename
error, and if
the name is to long IoErrorFilenameTooLong
will be returned. Other errors are possible too,
and depend on what kind of filesystem the file is on.
fileAppendToAsync :: FileClass file => file -> [FileCreateFlags] -> Int -> Maybe Cancellable -> AsyncReadyCallback -> IO () Source #
Asynchronously opens file for appending.
For more details, see fileAppendTo
which is the synchronous version of this call.
When the operation is finished, callback will be called. You can then call fileAppendToFinish
to get the result of the operation.
fileAppendToFinish :: FileClass file => file -> AsyncResult -> IO FileOutputStream Source #
Finishes an asynchronous file append operation started with fileAppendToAsync
.
fileCreateAsync :: FileClass file => file -> [FileCreateFlags] -> Int -> Maybe Cancellable -> AsyncReadyCallback -> IO () Source #
Asynchronously creates a new file and returns an output stream for writing to it. The file must not already exist.
For more details, see fileCreate
which is the synchronous version of this call.
When the operation is finished, callback will be called. You can then call fileCreateFinish
to
get the result of the operation.
fileCreateFinish :: FileClass file => file -> AsyncResult -> IO FileOutputStream Source #
Finishes an asynchronous file create operation started with fileCreateAsync
.
fileReplaceAsync :: (FileClass file, GlibString string) => file -> string -> Bool -> [FileCreateFlags] -> Int -> Maybe Cancellable -> AsyncReadyCallback -> IO () Source #
Asynchronously overwrites the file, replacing the contents, possibly creating a backup copy of the file first.
For more details, see fileReplace
which is the synchronous version of this call.
When the operation is finished, callback will be called. You can then call fileReplaceFinish
to get the result of the operation.
fileReplaceFinish :: FileClass file => file -> AsyncResult -> IO FileOutputStream Source #
Finishes an asynchronous file replace operation started with fileReplaceAsync
.
fileQueryInfo :: (FileClass file, GlibString string) => file -> string -> [FileQueryInfoFlags] -> Maybe Cancellable -> IO FileInfo Source #
Gets the requested information about specified file. The result is a FileInfo
object that contains
key-value attributes (such as the type or size of the file).
The attribute value is a string that specifies the file attributes that should be gathered. It is
not an error if it's not possible to read a particular requested attribute from a file - it just
won't be set. attribute should be a comma-separated list of attribute or attribute wildcards. The
wildcard "*" means all attributes, and a wildcard like "standard::*" means all attributes in the
standard namespace. An example attribute query be "standard::*,user
". The standard attributes
are available as defines, like FileAttributeStandardName
.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
For symlinks, normally the information about the target of the symlink is returned, rather than
information about the symlink itself. However if you pass FileQueryInfoNofollowSymlinks
in
flags the information about the symlink itself will be returned. Also, for symlinks that point to
non-existing files the information about the symlink itself will be returned.
If the file does not exist, the IoErrorNotFound
error will be returned. Other errors are
possible too, and depend on what kind of filesystem the file is on.
fileQueryInfoAsync :: (FileClass file, GlibString string) => file -> string -> [FileQueryInfoFlags] -> Int -> Maybe Cancellable -> AsyncReadyCallback -> IO () Source #
Asynchronously gets the requested information about specified file. The result is a FileInfo
object
that contains key-value attributes (such as type or size for the file).
For more details, see fileQueryInfo
which is the synchronous version of this call.
When the operation is finished, callback will be called. You can then call
fileQueryInfoFinish
to get the result of the operation.
fileQueryInfoFinish :: FileClass file => file -> AsyncResult -> IO FileInfo Source #
Finishes an asynchronous file info query. See fileQueryInfoAsync
.
fileQueryExists :: FileClass file => file -> Maybe Cancellable -> Bool Source #
Utility function to check if a particular file exists. This is implemented using fileQueryInfo
and as such does blocking I/O.
Note that in many cases it is racy to first check for file existence and then execute something based on the outcome of that, because the file might have been created or removed in between the operations. The general approach to handling that is to not check, but just do the operation and handle the errors as they come.
As an example of race-free checking, take the case of reading a file, and if it doesn't exist,
creating it. There are two racy versions: read it, and on error create it; and: check if it exists,
if not create it. These can both result in two processes creating the file (with perhaps a partially
written file as the result). The correct approach is to always try to create the file with
fileCreate
which will either atomically create the file or fail with a IoErrorExists
error.
However, in many cases an existence check is useful in a user interface, for instance to make a menu item sensitive/ insensitive, so that you don't have to fool users that something is possible and then just show and error dialog. If you do this, you should make sure to also handle the errors that can happen due to races when you execute the operation.
fileQueryFileType :: FileClass file => file -> [FileQueryInfoFlags] -> Maybe Cancellable -> FileType Source #
Utility function to inspect the FileType
of a file. This is implemented using fileQueryInfo
and as such does blocking I/O.
The primary use case of this method is to check if a file is a regular file, directory, or symlink.
fileQueryFilesystemInfo :: (FileClass file, GlibString string) => file -> string -> Maybe Cancellable -> IO FileInfo Source #
Similar to fileQueryInfo
, but obtains information about the filesystem the file is on, rather
than the file itself. For instance the amount of space available and the type of the filesystem.
The attribute value is a string that specifies the file attributes that should be gathered. It is
not an error if it's not possible to read a particular requested attribute from a file - it just
won't be set. attribute should be a comma-separated list of attribute or attribute wildcards. The
wildcard "*" means all attributes, and a wildcard like "fs:*" means all attributes in the fs
namespace. The standard namespace for filesystem attributes is "fs". Common attributes of interest
are 'FILEAttributeFilesystemSize (The Total Size Of The Filesystem In Bytes)',
'FILEAttributeFilesystemFree (Number Of Bytes Available)', and FileAttributeFilesystemType
(type of the filesystem).
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If the file does not exist, the IoErrorNotFound
error will be returned. Other errors are
possible too, and depend on what kind of filesystem the file is on.
fileQueryFilesystemInfoAsync :: (FileClass file, GlibString string) => file -> string -> Int -> Maybe Cancellable -> AsyncReadyCallback -> IO () Source #
Asynchronously gets the requested information about the filesystem that the specified file is
on. The result is a FileInfo
object that contains key-value attributes (such as type or size for
the file).
For more details, see fileQueryFilesystemInfo
which is the synchronous version of this call.
When the operation is finished, callback will be called. You can then call
fileQueryInfoFinish

Gets the requested information about the files in a directory. The result is a FileEnumerator
object that will give out FileInfo
objects for all the files in the directory.
The attribute value is a string that specifies the file attributes that should be gathered. It is
not an error if it's not possible to read a particular requested attribute from a file - it just
won't be set. attribute should be a comma-separated list of attribute or attribute wildcards. The
wildcard "*" means all attributes, and a wildcard like "standard::*" means all attributes in the
standard namespace. An example attribute query be "standard::*,user
". The standard attributes
are available as defines, like FileAttributeStandardName
.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If the file does not exist, the IoErrorNotFound
error will be returned. If the file is not a
directory, the FileErrorNotdir
error will be returned. Other errors are possible too.

The display name is converted from UTF8 to the correct encoding for the target filesystem if possible and the file is renamed to this.
If you want to implement a rename operation in the user interface the edit name
(FileAttributeStandardEditName
) should be used as the initial value in the rename widget, and
then the result after editing should be passed to fileSetDisplayName
.
On success the resulting converted filename is returned.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.

from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
fileCopy :: (FileClass source, FileClass destination) => source -> destination -> [FileCopyFlags] -> Maybe Cancellable -> Maybe FileProgressCallback -> IO () Source #
Copies the file source to the location specified by destination. Can not handle recursive copies of directories.
If the flag FileCopyOverwrite
is specified an already existing destination file is overwritten.
If the flag FileCopyNofollowSymlinks
is specified then symlinks will be copied as symlinks,
otherwise the target of the source symlink will be copied.
If cancellable is not Nothing
, then the operation can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If progressCallback
is not Nothing
, then the operation can be monitored by setting this to a
FileProgressCallback
function. progressCallbackData
will be passed to this function. It is
guaranteed that this callback will be called after all data has been transferred with the total
number of bytes copied during the operation.
If the source file does not exist then the IoErrorNotFound
error is returned, independent on
the status of the destination.
If FileCopyOverwrite
is not specified and the target exists, then the error IoErrorExists
is
returned.
If trying to overwrite a file over a directory the IoErrorIsDirectory
error is returned. If
trying to overwrite a directory with a directory the IoErrorWouldMerge
error is returned.

The native implementation may support moving directories (for instance on moves inside the same filesystem), but the fallback code does not.
If the flag FileCopyOverwrite
is specified an already existing destination file is overwritten.
If the flag FileCopyNofollowSymlinks
is specified then symlinks will be copied as symlinks,
otherwise the target of the source symlink will be copied.

from another thread. If the operation was cancelled, the error IoErrorCancelled
will be
returned.
If progressCallback
is not Nothing

error is returned, independent on
the status of the destination.
If FileCopyOverwrite
is not specified and the target exists, then the error IoErrorExists
is
returned.
If trying to overwrite a file over a directory the IoErrorIsDirectory
error is returned. If
trying to overwrite a directory with a directory the IoErrorWouldMerge
error is returned.
If the source is a directory and the target does not exist, or FileCopyOverwrite
is specified
and the target is a file, then the IoErrorWouldRecurse
error may be returned (if the native
move operation isn't available).
fileMakeDirectory :: FileClass file => file -> Maybe Cancellable -> IO () Source #
Creates a directory. Note that this will only create a child directory of the immediate parent
directory of the path or URI given by the File
. To recursively create directories, see
fileMakeDirectoryWithParents
. This function will fail if the parent directory does not
exist, setting error to IoErrorNotFound
. If the file system doesn't support creating
directories, this function will fail, setting error to IoErrorNotSupported
.
For a local File
the newly created directory will have the default (current) ownership and
permissions of the current process.
If cancellable is not Nothing
